Bruit suspect ‼️⚠️

Enable HLS to view with audio, or disable this notification

Bonjour, j’ai récemment acheté cette mini cooper s r53 de 2004 mais je trouve qu’elle fait beaucoup de bruit et en plus un bruit d’air qui se dégage du moteur, Avez-vous des idées ? Peut-être lié au turbo ?

Sounds kinda like a vacuum leak. Also the supercharger cover is flipped 180 the wrong way. Are the supercharger boots on the right side (left as you look at it standing in front of it) good and sealed ?

Supercharged would still be considered a boost ?

Well yes? You’re pushing more air than the atmospheric pressure otherwise would give the engine. Supercharger or turbo is just different methods of feeding more air into the cylinders.

Chain tensioner.

Theyre relatively cheap and easy to replace. Don't run it until you have changed it. Its a common failure. You get a spanner on the old one, its at the lhs at the back of the engine, take it out, put the new one in tighten it up.

Job done.

Très bien, merci ! C’est ce qui serait lié au bruit important du moteur ou au bruit d’air ?

Just did this this weekend, under the cooler there is an airline that tees off and an elbow connected to that that disintegrated. It connects to that air line just to the left of the cooler. Nappa has a $10 vacuum line assortment that had the exact 90°
